4 Protecting Yourself and Those Around You This machine was built to be operated according to the safe operation practices in this manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of amputating hands and feet and throwing debris. Failure to observe the following safety instructions could result in serious injury or death. Many accidents occur when more than one person operates the machine. No helper is allowed to assist in stacking logs. Operating this Log Splitter safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can create a number of hazards for you. Always take the following precautions when operating this Log Splitter: Always wear protective goggles or safety glasses with side shields while using the Log Splitter to protect your eyes from possible thrown debris. Avoid wearing loose clothing or jewelry, which can catch on moving parts. We recommend wearing gloves while using the Log Splitter. Be sure your gloves fit properly and do not have loose cuffs or drawstrings. Wear shoes with non-slip treads when using your Log Splitter. If you have safety shoes, we recommend wearing them. Do not use the machine while barefoot or wearing open toed sandals. Wear long pants while operating the Log Splitter. Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing. Safety for Children and Pets Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the machine and the splitting activity. Never assume that children will remain where you last saw them. Always follow these precautions: Keep children and pets at least 50 feet from the working area and ensure they are under the watchful care of a responsible adult. Be alert and turn the machine off if children or pets enter the work area. Never allow children to operate the Log Splitter. Hydraulic Safety High fluid pressures are developed in hydraulic machines. Pressurized hydraulic fluid escaping through a pin hole opening can puncture skin and cause severe blood poisoning. Therefore, the following Instructions should be heeded at all times. Do not operate the unit with frayed, kinked, cracked or damaged hoses, fittings, or tubing. Stop the engine, wait 5 minutes and relieve hydraulic system pressure by cycling the valve control lever from forward to reverse several times and returning to neutral while engine is not running before changing or adjusting fittings, hoses, tubing, or other system components. Do not change any Log Splitter relief valve settings. They are set at the factory for best Splitter performance and safety. Do not check for leaks with your hand. Leaks can be located by passing cardboard or wood over the suspected area: Look for discoloration. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immediately. Always wear safety glasses to protect your eyes from hydraulic fluid. NEVER remove the cap from the hydraulic tank or reservoir while the log splitter is running. The tank could contain hot oil under pressure which could result in serious injury. 4 DR VERTICAL/HORIZONTAL LOG SPLITTER

5 Safety with Gasoline - Powered Machines Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or explosion. Never overlook the hazards of gasoline. Always follow these precautions: Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon monoxide, which is an odorless, tasteless, and deadly poisonous gas. Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open flame, and out of the reach of children. Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use. Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank cap and fuel container cap securely and Never remove gas cap while the engine is hot or running. If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the waste. Allow the engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace. Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping it away from the spark plug to prevent accidental starting, wait 5 minutes before making adjustments, repairs or refueling. Never tamper with the engine s governor setting. The governor controls the maximum safe operation speed and protects the engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the machine. If required, see your authorized dealer for engine governor adjustments. Keep combustible substances away from the engine when it is hot. Never cover the machine while the muffler is still hot. Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could create a fire hazard. Do not use flammable solutions to clean the air filter. The muffler and engine become very hot and can cause a severe burn; do not touch. Towing ALWAYS check before towing to make certain your Splitter is correctly and securely attached to the towing vehicle. Be sure that the ball hitch you are using is the proper size for the hitch coupler on the machine. Be sure the safety chains are properly hooked to the vehicle leaving enough slack for turning. Always use a Class I, 2 ball with this log splitter and replace the ball or coupler if damaged. Always confirm coupler tightness each time before towing and after towing 50 miles. ALWAYS use accessory lights and devices when transporting on a road or highway to warn operators of other vehicles. Check your local government regulations for DOT information. ALWAYS allow for added length of the Splitter when turning, parking, crossing intersections, and in all driving situations. ALWAYS be careful when backing up. You could jackknife your Splitter if care is not taken. NEVER exceed 45 mph. when towing your Splitter. Obey all state and local regulations when towing on state and local roads and highways. Adjust your speed for terrain and conditions, as needed. Be extra cautious when towing over rough terrain, especially over a railroad crossing. NEVER allow anyone to sit or ride on your Splitter. NEVER carry any cargo or wood on your Splitter. Do travel slowly over rough terrain, on hillsides, and around curves to prevent tipping. Do not tow the Splitter near the edge of a ditch or excavation. ALWAYS turn the fuel shut off valve on the engine to the OFF position before towing the log splitter. Failure to do so may result in flooding the engine. CONTACT US AT 5

19 Adjusting the Throttle Linkage After you have the Log Splitter fully assembled, the Throttle Linkage of the Subaru (9HP) Engine will need further adjustment. This procedure must be done before operating your Log Splitter. The following information explains the adjustment procedure. RUN IDLE Tools needed: Ratchet with Extension 10mm Socket Throttle Lever 1. Move the Throttle Lever to check if it will stay in the RUN position or if it returns to the IDLE position (Figure 13). 2. If the Throttle Lever stays in the RUN position then adjustment is not needed. 3. If the Throttle Lever returns to the IDLE position, go to the next step. 4. Use the Ratchet and Extension with the 10mm Socket to tighten the Throttle Linkage Nut until the Throttle Lever will stay in the RUN position (Figure 14). Note: The Throttle Lever Nut should be tight enough to hold the Lever in the RUN position while operation of the Log Splitter but not so tight that it is difficult to move the Lever back to IDLE position by hand. Figure 13 Throttle Linkage Nut SET UP Gas and Oil Fill-Up Service the engine with gasoline and oil as instructed in the engine manual packed with your log splitter. Read the instructions carefully. Figure 14 Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel the machine indoors or while the engine is hot or running. You must add oil before starting the engine. This machine is shipped without oil. Traces of oil may be in the reservoir from factory testing, but you must add oil before starting the engine. Fill the reservoir slowly, checking the level frequently to avoid overfilling. Note: Your log splitter is NOT shipped with motor oil in the engine. You MUST add oil before operating the splitter for the first time and check the oil level before each use. Be careful not to overfill. Gasoline can be added to the engine when the log splitter is in either the horizontal or vertical position. However, it may be easier when the splitter is in the vertical position. Tire Pressure The max recommended operating pressure is shown on the side of the Tire. Never exceed the manufacturer s recommended psi. Maintain equal pressure on all tires. Excessive pressure when seating beads may cause tire/rim assembly to burst with force sufficient to cause serious injury. CONTACT US AT 19

20 Preparing the Log Splitter 1. Lubricate the beam area (where the splitting wedge will slide) with engine oil. Do not use grease (Figure 15). (Figure 15) HYDRAULIC OIL ISO RECOMMENDATIONS 2. Fill hydraulic oil before your initial use. Tools and Supplies Needed: Paper Towels Hydraulic Fluid (see table-1) Note: you MUST check the fluid level before each use. If not touching the bottom portion of the dippstick, proceed with the following steps: 0 10 (-18 ) (-12 ) ISO (-7 ) ISO (-1 ) 40 (4 ) ISO (10 ) 60 (16 ) ISO (21 ) TEMPERATURE FAHRENHEIT (CELSIUS) Table-1 80 (27 ) 90 (32 ) You must add hydraulic fluid before using the splitter. This machine is shipped without hydraulic fluid in the hydraulic tank. When performing the following procedures, fill the hydraulic tank slowly, checking the level frequently to avoid overfilling. To get an accurate reading when checking the hydraulic fluid level: - the machine should be on a level surface. - the dipstick should be pushed in fully to ensure an accurate fluid level reading. Much of the original fluid has been drawn into the cylinder and hoses. Make certain to refill the reservoir to prevent damage to the hydraulic pump. DO NOT OVERFILL. 20 DR VERTICAL/HORIZONTAL LOG SPLITTER

21 a) Remove the vented reservoir dipstick, which is located next to the engine on top of the reservoir tank (Figure 16). (Figure 16) b) Check the fluid level using the dipstick. Also refer to (Figure 25 and Figure26 on Page29). c) Replace the vented dipstick. d) Make sure the Engine is in the STOP position and disconnect the spark plug wire from the spark plug. Prime the pump by pulling the recoil starter as far as it will go. Repeat approximately 10 times. e) Reconnect the spark plug wire and start the engine, following instructions in Chapter 3. f) Use the control handle to engage the wedge to the farthest extended position. Then retract the wedge. g) Refill the tank as needed so the fluid just touches the end of the dipstick. Note: Failure to refill the tank will void the splitter s warranty. h) Extend and retract the wedge 12 complete cycles to remove any trapped air in the system (the system is selfbleeding i) Refill the tank as needed so the fluid just touches the end of the dipstick.

22 Chapter 3: Operating The DR VERTICAL/HORIZONTAL LOG SPLITTER Operator Zone ONLY operate the log splitter from the operator zone as shown in the diagram. The operator has the safest and most efficient access to the control valve and the beam in this location. Operating the log splitter in another location can result in serious injury or death Keep the operator zone and adjacent area clear for safe, secure footing. Horizontal Operating Position: Stand on the control lever side of the log splitter and stabilize log (Figure 17). (Figure 17) Operator Zone Vertical Operating Position: Stand in front of the log splitter and stabilize log (Figure 18). (Figure 18) Operator Zone 22 DR VERTICAL/HORIZONTAL LOG SPLITTER

23 Handling Logs: Both ends of the log should be cut as square as possible to help prevent the log from riding out of the splitter during operation. Uneven logs (e.g. knotted, curved, etc.) should not be used. For logs which are not cut square, the least square end of the log should be placed toward the beam and wedge, and the square end placed toward the end plate. NEVER try to split two logs on top of each other. NEVER try to cross split a log. Do not place your hands on the ends of the log when loading the Log Splitter. This is a very UNSAFE method and could result in injury to your hands. Do not reach or step across the rail while the Log Splitter is running. This is a very UNSAFE method which could cause personal injury or even death. Never attempt to split wood across the grain. The Log Splitter was not designed for cross-grain splitting. Doing so could damage the Log Splitter and may cause personal injury. Make sure both ends of the log you are splitting are cut as square as possible. This will prevent the log from sliding out of position while under pressure. When loading a log, always place your hands on the side of the log, not on the ends, and never use your foot to help stabilize a log. Failure to do so, may result in crushed or amputated fingers, toes, hand, or foot. When stabilizing log with left hand, remove your hand when the wedge just contacts the log or serious injury may occur. NEVER place hands or feet between the log and splitting wedge during forward or reverse stroke as this could result in serious injury or death. NEVER attempt to load the log splitter when the ram or wedge is in motion. Always keep fingers away from any cracks that open in the log while splitting. They can quickly close and pinch or amputate your fingers. Never attempt to remove partially split wood from the wedge with your hands. Fully retract the wedge to dislodge wood with log dislodger.

24 Starting and Stopping the Engine Refer to the Engine Operator s manual packed with your log splitter for instructions on starting and stopping the engine. Beam Operating Positions 1. Place the log splitter on flat, dry, solid ground in a clean work area. 2. Block the front and back of both wheels (Figure 19). (Figure 19) 3. Place the beam in either the horizontal or vertical position and lock into place. Take extra care when raising and lowering the beam as it is fairly heavy. Having a second person assist with raising or lowering the beam is recommended. Be sure to keep hands away from any possible pinch points. Always use the log splitter in the vertical position when splitting heavy logs. 4. To place the beam in the Vertical Position proceed as follows: a) Pull the horizontal beam lock out to release the beam and pivot the beam to the vertical position (Figure 20). b) To lock the beam in the vertical position, pull out on the vertical beam lock and rotate it to secure the beam (Figure 21). 5. To place the beam in the Horizontal Position proceed as follows: a) Pull the vertical beam lock out and rotate it down. Pivot the beam to the horizontal position (Figure 21). b) The horizontal beam lock is self-locking. The spring loaded lock will snap into place when the beam is lowered into position.

25 Using Control Handle The control handle has three positions (Figure 22). Neutral Forward Reverse (Figure 22) FORWARD To split wood. Move the control handle to the FORWARD position to move wedge toward the log to split. Note: The control handle will return to the NEUTRAL position as soon as the handle is released (FORWARD position only). NEUTRAL To stop wedge. Release the control handle or move the lever to the NEUTRAL position to stop the wedge movement. REVERSE To return the wedge. Move the control handle to the REVERSE position to return the wedge toward the cylinder. The control handle returns to the NEUTRAL position automatically when fully retracted. Do not hold the handle in the REVERSE position when fully retracted. Note: To stop the wedge before the ram is fully retracted when in the REVERSE position, the handle must MANUALLY be put in the NEUTRAL position. If the control handle on your log splitter is not functioning properly, STOP USE IMMEDIATELY and contact an authorized service dealer. Do not attempt to service, repair or replace control valve. Contact an authorized service dealer. Do not attempt to adjust or modify the control valve or the hydraulic system from its original settings or manufacturer in any way. CONTACT US AT 25

26 Splitting The Wood 1. Start the engine as instructed in the Engine Operator s manual included with the log splitter. 2. Place the log against the end plate and only split the wood in the direction of the grain (Figure 23). 3. To stabilize the log, place your left hand on the side of the log opposite the beam. Never place a hand on the ends of the log, between the log and the end plate or the log and the splitting wedge. Only one operator permitted. The adult who loads and stabilizes the log, must be the person who operates the control handle. Remove split wood around the log splitter immediately so that you don t stumble over it. 4. Move the control handle to the forward position to split the wood. 5. Remove left hand from the side of the log once wedge just contacts the log. Continue moving control handle forward to split the log. 6. Release the control handle to stop the wedge movement. 7. Move the control handle to the reverse position to return the wedge. Right Hand Left Hand (Figure 23) 8. Remove partially split wood from wedge. a) Move the control handle to the REVERSE position until the wedge is fully retracted to allow split wood portion to contact the log dislodger. Never remove partially split wood from the wedge with your hands. Fingers may become trapped between the split wood. b) Once removed from the wedge with the log dislodger, split the wood from the opposite end or in another location. When splitting in the vertical position, stabilize the log before moving the control handle. Split as follows: 26 DR VERTICAL/HORIZONTAL LOG SPLITTER

27 a) Place log on the end plate and turn until it leans against the beam and is stable. b) When splitting extra-large or uneven logs, the log must be stabilized with wooden shims or split wood placed between the log and end plate or ground NEVER use your foot, a rope or any extension device to operate the control lever on the valve. Only use your right hand. Transporting The Log Splitter NEVER move the log splitter while the engine is running. Shut off the engine if you are leaving the log splitter, even for a short period of time. ALWAYS be careful when moving or lifting the log splitter. Get assistance if it feels too heavy to move by yourself. Move the fuel shutoff to OFF before towing the Wood Splitter. 1. Lower the beam to its horizontal position. Make certain the beam is locked securely with the horizontal beam lock. 2. Change the jack stand to transporting position (Figure 24). a) Remove the spring clip and clevis pin from the jack stand. b) Support the tongue and pivot the jack stand up against the tongue. c) Secure with the spring clip and clevis pin previously removed. Clevis Pin Spring Clip (Figure 24) Jack Stand 3. Attach the coupler hitch to a class I or higher 2 ball on the towing vehicle latch securely. a) If the coupler hitch does not fit on the ball, turn the adjustment nut one turn counter-clockwise. b) If the coupler hitch is too loose on the ball, turn the adjustment nut one turn clockwise. Then recheck and adjust accordingly. 4. Connect the safety chains to the towing vehicle. Do not tow faster than 45mph and check the local, state and federal requirements before towing on any public road. Use caution when backing up, using a spotter outside the vehicle is recommended. ALWAYS disconnect your log splitter from the towing vehicle before operating it. CONTACT US AT 27

28 Chapter 4: Maintaining The DR VERTICAL/HORIZONTAL LOG SPLITTER Regular maintenance is the way to ensure the best performance and long life of your machine. Please refer to this manual and the engine manufacturer's owner's manual for maintenance procedures. Service intervals listed in the checklist below supersede those listed in the engine manufacturer's owner's manual. Before performing any maintenance procedure or inspection, stop the engine, wait five (5) minutes to allow all parts to cool. Disconnect the spark plug wire, keeping it away from the spark plug. Refer to the Engine Operator s manual packed with your log splitter for all engine maintenance. Regular Maintenance Checklist PROCEDURE BEFORE EACH USE EVERY 25 HOURS EVERY 50 HOURS EVERY 100 HOURS Check Engine Oil Level Check General Equipment CPerform di i Rail Maintenance Check Hydraulic Fluid Level Check Tire Pressure Clean Engine Exterior and Cooling Fins Change Engine Oil 1 st time 5 hours Replace Air Filter Replace Hydraulic Filter Change Hydraulic Fluid Replace Spark Plug Engine Service Refer to the Engine Operator s manual packed with your log splitter for all engine maintenance.

29 Hydraulic Filter Change the hydraulic filter every 50 hours of operation. Use only a 10 micron hydraulic spin-on filter, or buy from an authorized dealer. Order part # 51 in Exploded Diagram. Flexible Pump Coupler The flexible pump coupler, located between the pump and the engine shaft, has a nylon spider insert. Over time, the insert will harden and deteriorate. If you detect vibration or noise coming from the area between the engine and the pump, contact us at or call toll-free DR-OWNER ( ) for assistance. Change a new coupler immediately (refer to the pump assembly STEP 4 in Page 12), if the coupler fails completely, you will experience a loss of hydraulic power. Hydraulic Fluid Check the hydraulic fluid level in the log splitter reservoir tank before each use. Maintain the fluid level within the range specified on the dipstick at all times. Change the hydraulic fluid in the reservoir every 100 hours of operation. The filter should also be changed with each hydraulic fluid change. Follow the steps below: 1. Place a suitable oil collection container under the tank. Allow the fluid to drain into the container. Note: The hydraulic system has a capacity of 4 gallons of hydraulic fluid for 22 Ton and 28 Ton; and 5 gallons for 34 Ton. (Figure 25) (Figure 26) 2. After draining, screw on the oil drain screw and tighten. 3. Refill the reservoir tank (Please follow the steps in Page to fill the tank, and repel the air in the tank). The fluid should be just touching the end portion of the dipstick. 4. Maintain the fluid level within the range specified at all times (Figure 26). Note: When checking the fluid, always make sure to install the dipstick and push it down fully. Note: Always dispose of any used hydraulic fluid and engine oil at approved recycling centers only. Contaminants in the fluid may damage the hydraulic components. Beam and Splitting Wedge Lubricate top, sides and bottom of the beam and where it comes into contact with the splitting wedge with engine oil before each use. If the wedge becomes dull or nicked, it can be sharpened. CONTACT US AT 29
